Abstract: ABSTRACT OF THE DISCLOSURE            A radioassay system for the determination of methotrex-ate in biological fluids based on the competitive binding of labeled and unlabeled methotrexate to the enzyme dihydrofolate reductase.  Samples of unknown methotrexate level are mixed with a labeled methotrexate particularly an I125 labeled methotrexate.          A portion of the total methotrexate present is bound by the addi-tion of enzyme, and the unbound methotrexate is removed with char-coal.  The level of bound I125 labeled methotrexate is measured in a gamma ray counter.  To calculate the methotrexate level of the unknown samples, the displacement of bound labeled methotrex-ate caused by the unknowns is compared to the displacement caused by known methotrexate standards.

Abstract: Abstract of the Disclosure Disclosed in this specification is a charge coupled device in which the charge is transferred over a meandering route in the channel and there is at least one bend in the channel.  The channel bending angle can be as much as 180°. When the channel bending angle is less than 180°, the channel can be formed into a ring formed by several bends.  In any case, the gate electrode takes a simple rectangular form and it is also bent at the same angle with the channel where the channel is bent.  In the case where the channel is bent 180°, the signal injected from the input end is transferred to the area adjacent to the input end and the signal can be injected again to the input end for circulation after it is once amplified.

Abstract: ABSTRACT OF THE DISCLOSURE         An electrochemical cell is disclosed for eliminating and/or recovering dissolved metals from waste liquors or winning dissolved metals from waste solutions having a low concentration of such metals.  The cell has a three dimensional electrode with a geometrical bed depth that is increased from the electrolyte inlet to outlet so that the bed depth increases along the flow direction corresponding to the concentration decrease within the cell.  Thus, the geometrical bed depth is essentially equal to the effective bed depth at each point within the electrode where the electrochemical conversion takes place.

Abstract: DUAL MODULUS PROGRAMMABLE COUNTER     ABSTRACT OF THE DISCLOSURE    The inventive counter is operable to divide an input signal by the sum of two binary numbers, A and B.  Each number is stored in memory.  These numbers are alternately preset into a binary counter which also receives the input signal.  A logic gate monitors the counter output and changes state when the number previously preset in the counter equals the accumulated count.  The gate state transition is used to preset the counter with the alternate stored number.          Thus, the process continues whereby the output from the logic gate represents the input signal divided by the sum of A and B.

Abstract: ABSTRACT OF THE DISCLOSURE          In an expansion dowel assembly, a stud or bolt extends through an expansion sleeve with an expending body on one end for radially spreading the sleeve and a head or first working part on the other end for applying torque.  A second working part encloses the first working part and is attached to it by one or more shear members.  Torque for anchoring the sleeve in a borehole is applied through the second working part to the first working part and the stud.  When a preset torque is reached, the shear members break and the second working part can move relative to the first working part without transmitting torque to tile stud.  A separating member is provided between the first and second working parts and after the preset torque is attained, further torque cannot be applied to the stud until the separating member is removed.  Preferably, the separat-ing member consists of a flange with outstanding fingers which are in contact with the surface of the first working part against which a torque applying tool is placed.  Removal of the fingers is necessary before torque can be applied to the first working part.

The aspirator includes a housing having a tunnel therein, which is spaced from an ink jet nozzle which emits an ink jet stream which passes through the tunnel.  A gas stream is also directed through the tunnel at substantially the same velocity as the ink jet stream for reducing the aerodynamic effects on adjacent ink droplets.  The tunnels cross-sectional area is substantially constant from one plane to the next when measured in any given plane transverse to the longitudinal axis, for maintaining the velocity of the gas stream constant.  The tunnel has a circular cross-section when used in a nozzle per spot system, and when used in an analog deflected system, has an entrance of one geometry, with the tunnel changing in geometry along its longitudinal axis to a different geometry at its exit.  Preferably, in the analog deflected system, the entrance geometry is circular and the exit geometry is elliptical or rectangular.
